Subject [jira] Commented: (HTTPCLIENT-911) Support underscore in domain name, or provide better exception
Date Tue, 27 Jul 2010 14:25:17 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-911?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12892794#action_12892794
] 

Mingfai Ma commented on HTTPCLIENT-911:
---------------------------------------

Just come across this issue myself. second level domain name may not use underscore but there
are websites in real life use underscore in their subdomain, and it doesn't make sense if
we can't make connection to them with a Java library while people can connect to it with browser.
Ideally, httpclient should just handle those URL with underscore, maybe we shouldn't rely
on URI.

> When calling on HttpClient.execute with a url that contain underscore ('_'), you get
NullPointerException.
> Tracing it down show that java.net.Uri complains that it is illegal name. Which is true
according to the RFC.
> But it seems that most browser allow it, and some companies support it.
> I think HttpClient should either support underscores, or atleast provide a better exception.
